CVE-2024-26955
Estado: AnalizadaAlta (7.8)—
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: nilfs2: previene el error del kernel en submit_bh_wbc(). Se corrige un error por el cual nilfs_get_block() devuelve un estado exitoso cuando la búsqueda y la inserción del bloque especificado fallan de manera inconsistente. Si este comportamiento inconsistente no se debe a un error solucionado previamente, entonces se está produciendo una ejecución inesperada, por lo que se devuelve un error temporal -EAGAIN. Esto evita que llamadores como __block_write_begin_int() soliciten una lectura en un búfer que no está asignado, lo que provocaría que falle la verificación BUG_ON del indicador BH_Mapped en submit_bh_wbc().
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 7.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.26%
- Percentil entre todas las CVEs puntuadas: 16
- Fecha de la puntuación: 8/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
